     On your IIgs, you can use DSK2FILE or ASIMOV to convert the .dsk file to
diskette form. You can find these utils at ...

     Here is a quickie step-by-step guide for getting a 5.25" .dsk disk image
file into useable form:


1. Download the file in binary mode from an ftp archive site via ftp:// ...

2. If file length is not 143,360, use WinZIP or equivalent to unZip it.

3. Transfer the DSK file to your GS via Mac diskette or a NULL modem transfer.
One way or another, the file needs to end up on a ProDOS diskette or ProDOS
hard disk volume on the GS.

4. The vast majority of DSK files are images of DOS 3.3 diskettes. Unless you
have good reason to believe the DSK is an image of a ProDOS diskette, format or
INIT a 5.25" diskette for DOS 3.3. (If the DSK file has a .PO suffix or if you
have good reason to believe the DSK is an image of a ProDOS diskette, format
the target diskette for ProDOS.)

If you are using DSK2FILE, now is a good time to jot down the complete path
name of the DSK file (e.g. /RAM5/NARFGAMES.DSK ) because DSK2FILE will ask you
to type it in.

5. Insert the formatted target diskette into 5.25" Drive 1 (Slot 6).

6. Start DSK2FILE or ASIMOV. Normally, you will accept the defaults. (If the
DSK is a ProDOS image, select "ProDOS Order".)  

7. Select the "Image file ---> Diskette" option, follow prompts, and you should
end up with a good diskette.
